    keyword=Re: EDTM time offset, L-HRS

    A measurement on the scope of the time between the frontend output
    of the EDTM (which goes to discriminators) and the backend output,
    which goes to BigBite.

    The backend output is earlier by 118 ns for the master (S2 EDTM).

    The internal delay of the slave EDTM for S1 is 190 ns.

    I measured the additional delay due to using the back output of the slave
    for BigBite to be 24 ns, this includes the 6 ns cable between the master
    output and slave input.

    Total delay for BigBite EDTM signal on L-HRS is

    16 ns cable
    8 ns 754 module
    5 ns cable
    260 ns RG-58 cable #5
